MXenes have received worldwide attention across various scientific and technological fields since the first report of the synthesis of Ti3C2 nanostructures in 2011. The unique characteristics of MXenes, such as superior mechanical strength and flexibility, liquid-phase processability, tunable surface functionality, high electrical conductivity, and the ability to customize their properties, have led to the widespread development and exploration of their applications in energy storage, electronics, biomedicine, catalysis, and environmental technologies. The significant growth in publications related to MXenes over the past decade highlights the extensive research interest in this material. One area that has a great potential for improvement through the integration of MXenes is sensor design. Strain sensors, temperature sensors, pressure sensors, biosensors (both optical and electrochemical), gas sensors, and environmental pollution sensors targeted at volatile organic compounds (VOCs) could all gain numerous improvements from the inclusion of MXenes. This report delves into the current research landscape, exploring the advancements in MXene-based chemo-sensor technologies and examining potential future applications across diverse sensor types.

“…Humidity sensors are an important type of environmental sensor used for humidity measurement in a wide range of applications, from hygrometers, home appliances, and other everyday items to industry and agriculture, aerospace, or biological system control. [1][2][3] Humiditysensitive materials employed in these sensors include polymers, ceramics, semiconductors, and other substances; particularly, ceramic-based humidity sensors enjoy wide use due to their thermal, chemical, and mechanical stability. Thus, many studies are carried out on ceramicbased humidity sensors toward faster response and wider range.…”

In this study, iron oxide thin films are prepared under various heat treatment conditions, and their crystal structures and moisture‐sensitive characteristics were evaluated to clarify the usefulness of iron oxide thin films as humidity‐sensitive materials for humidity sensors. In addition, the possibility of a humidity sensor with a wide dynamic range was investigated by evaluating the relationship between the film thickness of the iron oxide thin film, the electrode width of the device, and the humidity‐sensitive characteristics. As a result, it was found that the crystal structure of α‐Fe2O3 exhibits relatively good humidity sensitivity compared to other crystal structures, and that the sensitivity to humidity can be adjusted by appropriately selecting the electrode width and film thickness of the device. Therefore, the α‐Fe2O3 thin film may be useful as a moisture‐sensitive material for wide dynamic range humidity sensors by appropriately adjusting the film thickness and electrode width.
